ARTHUR JOHNSON, or namenronr, commcrrcu'r mmormme Application filedOctober 25, 1929, Serial No. 402,408. Renewed September 28, 1981.

This invention relates to manifolding, and more particularly, to a pileof manifolding material made up of a plurality of continuous worksheetstrips, each having a succession of forms, and a carbon stripinterleaved between each two adjacent worksheet strips.

Heretofore, it was proposed to have such worksheet strips andcarbonsheet strips secured together at intervals along the stripsbystaples or other means so as to hold the strips in registrationpreparatory to and during the operation of writing upon a pile ofstrips; and it.was also proposed to have the securing means so locatedthat it would hold the written set of forms together in booklet form forsubsequent writin operations or for handling. In one of suc previousproposals, the forms were transversely perforated between the bodythereof and the se cured portion so as to permit the inside leaves ofthe booklet to he removed as desired and without necessitatingtheremoval of the outside leaves, or any of the other leaves, but allowinga stub to remain attached to the other leaves.

An object of the present invention is to provide a manifolding pack inwhich the strips are so secured together that the leaves in the booklet,resulting from severing a set of forms from the continuous pile, may beremoved at will without disturbing any of the other leaves and withoutnecessitatin the provision of the transverse line of per ora- 35 tionsand permitting the entire form to be kept intact.

This is accomplished, according to the present invention, by providingstaples in the pile of worksheetsone located so near 49 one edge of eachset of forms that by pulling on the lower edge of the form to beremoved, the material of the form between the legs of the staples andthe adjacent edge of the form will be slit 'to permit the form beingremovedto slip by the staple. The

staple is preferably placed longitudinally of the strip so that the twolegs of the staple lie in the same longitudinal line and, hence only oneslit need be made to permit removal of the form.

Another feature of this'invention isthe provision of means forfacilitating the formation of the slit by the pulling action on the formto be removed, and this is accomplished by providing a weakenedline orlines 0f perforations running from the legs of the staple to theadjacent edge of the form. When this is done, the staple may be placedfurther from the edge of the form than without it, audit is preferablethat the staple be placed longitudinally of the strip, for then only oneline of perforations communicating with the edge of the strip need beprovided instead of two which would be used'in case the staple islocated transversely of the strips. 5

' Other features and advantages will here: inafter appear.

' repr As shown in the accompanying drawings, the manifolding pile ofthe present invention comprises a pluralit of superposed worksheetstrips 10 each 0 which may have a continuous succession of printed forms11. In-

' terleaved between each two adjacent worksheet strips 10 is a' carbonstrip 12 sothat writin performed on the top strip 10 Wlll be uced on theunder strips 10 through the medium of the carbon strips 12.

To receive said writing operations, the worksheet strips 10 are perposedrelatlon, one a the printed forms 11 on one strip registering with thoseof the other strip or strips.

To hold the worksheet strips 10 in said proper superposed registeringrelation and to hold the carbon strips in their proper 0- sitionsrelative to the worksheet strips a er the strips are superposed, theyare secured together by means placed at intervals along the pile ofstrips.

According to .the present invention, these means comprise staples 13which extend throu h all the strips of the pile and have their legs 14bent over at one side to hold the staples in place against unintentionalremoval. These staples hold the strips together preparatory to andduring the operation of writing upon the strips.

After a set of forms has been written upon. as for instance, inatypewriting machine, the se is severed from the next ,set in the pilealong lines of perforations 15 separating one form on each strip fromthe next.

Heretofore, it was proposed to locate the staple 13 on the lines ofperforations 15 so that the staple would become inoperative to hold thestrips together after the written set was severed from the pile.

' In some classes of work, however, it is deslrable to keep the severedset intact, at least temporarily, until certain data, which can only beobtained after the writing operation, has been filled in-say, forinstance, in the spaces 16 on the kind of form illustrated herein. Someof this information is writ ten on all of the strips of the set, afterwhich the set of strips while still intact is transferred from oneperson to another interested in the transaction and these persons maketheir notations on" certain of the strips and that the first form to beremoved is either to be removed is next to it and so on. But,since-certain of the data should be filled in by one person or anotherin the sequence,

this arrangement is not always convenient,

placed in proper su-, ove the other, wlth' vention provides means forpermitting the removal of any one of the forms in the set or booklet,which results from the severing of one set of forms from the next,without necessitating the removal of any of the other forms and permitsthe removal of the form desired in its entirety instead of allowing astub to remain with the set as was heretofore proposed.

This is accomplished by the present invention by providing the staples13 at the head of theforms constituting a set in such a way that one ormore slits are produced between the point at which the staple is locatedand the adjacent edge of the form when the form to be removed is graspedand pulled from the booklet.- This may be done as shown in Fig. .7 byplacing the staple 13 so close to the adjacent edge 18 of the form thatwhen the form is pulled a slit is torn in the form by the legs 14 of thestaple, so that the form to be removed may slip by the staple whenpulled. The staple may be placed transversely of the sheet, in whichcase each leg 14 would produce a slit, but it is referable that it beplaced longitudinally o the form so that the legs of the staples willproduce only one slit.

The forming of the slit through which the staple legs may pass duringthe extraction of one form may be facilitated by producing weakeninglines between the points where the legs of the staple are located andthe adjacent edge 18 of the form or leaf, as, for instance, the lines ofperforations 17 illustrated in Figs. 1, 2 and 6 herein, so that when theform to be extracted is pulled, the

fabric of which it is constituted will break down between theperforations 17 and easily form a slit permitting the form to slip bythe staple.

In this case also, the staple may be placed I transversely of the formas shown in Fig. 6, in which case, however, two lines of perforations 17leading from the legs 14 of the staple extend to the adjacent edge 18 ofthe form. It is therefore preferable that the staple lie longitudinallyof the strip as shown in Figs. 1 to 4, for then only one. line ofperforations 17 need be provided.

When the forming of the slit in the leaf to be extracted is facilitatedby the preparation of the forms with the perforations 17, the staple maybe set inwardly farther from the edge 18 of the form than otherwise, andthe leaves, particularly the upper and lower leaves, are therefore lesslikely to be accidentally torn from the booklet when the embodiment ofthe invention illustrated in Figs. 1 to 4 is emplo ed.

As illustrated in i 2, the line of perforations 17 extends to the leg 14of the staple which is most remote from the line of severance 15 so thatat the beginning of the extracting operation, both legs of the stapletear through the ties 19 between the perforations 17 in causing the slitto be formed from the point of location of the most remote leg H to theedge 18 of the form.

Other. variations and modifications may be made within the scope of thisinvention and portions of the improvements may be used without others.

Having thus described the invention, what is claimed as new and forwhich it is desired to obtain Letters Patent, is
